How to resize the container view with respect to its embedded view controller?

Question

I want to resize the superview with respect to its subview.

The scenario is that I have a scroll view inside it there is a view with different subviews. Within the subviews, there is a ContainerView with embedded view controller. Which have a table view. I want to increase the size of the table view as the cell increases and in the same the increase the height of view- container - view and scroll view, Because the table wont scroll.

i was able to increase the size of the table view following the link enter link description here

but i am stuck how can i increase the size of the embedded view.

To elaborate more i am attaching images from a project i am practicing on.

• Purple is the color of the main view controller.
• Green is scroll view.
• Grey is view inside scroll view.
• Blue is the color of embedded View controller.

• Red is the color of table view. but cant be seen on simulator as it has resized according to the number of cells.

  -(CGSize)sizeForChildContentContainer:(id<UIContentContainer>)container
             withParentContainerSize:(CGSize)parentSize
  {
  
       //    int height = _containerView.frame.size.height;
       NSLog(@"height of container");
       return _tableView.frame.size;
  }
  
  -(void)adjustHeightOfTableview
  
  {
  
       CGFloat height =  self.tableView.contentSize.height;
       CGFloat maxHeight = self.tableView.superview.frame.size.height -  self.tableView.frame.origin.y;
  
  
       // if the height of the content is greater than the maxHeight of
       // total space on the screen, limit the height to the size of the
       // superview.
  
      if (height > maxHeight)
          height = maxHeight;
  
      // now set the height constraint accordingly
  
      [UIView animateWithDuration:0.25 animations:^{
         self.tableViewHeightConstraint.constant = height;
         [self.view setNeedsUpdateConstraints];
  
      }];
  
      [_tableView setNeedsLayout];
      [_tableView layoutIfNeeded];
  }
  

In the same way or some thing like that i need to resize the view. I have searched for some thing similar but i did not got a clear answer, any kind of help will be appreciated.
